Figure 6 is a section on line 6--6 Figure l, and

Figure 7 is a section on line 'l-1 Figure 3.

The stand includes a sustaining element I, a. hinged bracing element 2, a hinged supporting element 3, a securing element 4 and a combined pulling and coupling element 5. The elements l, 2, 3 and 4 preferably will be constructed from cardboard of the desired thickness and rigidity, but it is to be understood that such elements may be formed from any suitable material.

The element I is of rectangular contour and of the desired length and width. When element I is active, it is disposed in an upstanding manner and inclines rearwardly from its bottom to its top. The purpose of element I is to sustain the music sheets in an upstanding rearwardly inclined position so the music may be conveniently readby the scholar.

The bracing element 2 is of truncated tapered form, has a straight top edge 6 and a straight bottom edge l. The latter is of greater length than edge 6. The element 2 is of less length than the length of and is arranged rearwardly of the element I. Element 2 has its top edge 6 spaced from and arranged below the upper lengthwise edge 3 of element I and its bottom edge 'l spaced from and arranged above the lower lengthwise edge 9 of element I.

Secured to the rear face of element I, below and in proximity to edge 8, as Well as being disposed centrally of such face is a spacer strip I0. Spaced holdfast means I I are employed for securing the strip IIJ to element I. The topy edge 6 of element 2 is arranged in juxtaposition to the bottom edge of strip I0. The latter is preferably formed of 50 cardboard and is of a thickness corresponding to the thickness of element 2. The latter is hinged to the strip I0 by any suitable means, such as a strip of thin fabric I2 secured to the rear surfaces of the element 2 and stripy l0 by any suitable ad 55k section `I holdfast means I6.

fined between elements 3, 4.

hesive material. The hinge between element 2 and strip I preferably will be provided by a length of adhesive tape.

'I'he supporting element 3 is of oblong form, arranged forwardly o-f and has its side edges flush with the side edges of the element I. The lower lengthwise edge I3 of element 3 is arranged above and in proximity to the edge I of element I. When element 3 is extended with respect to ele.- ment I its 'lower lengthwise edge I3 abuts the front surface of element I above the edge 'I of the latter. When element 3 is extended it is disposed at an upward inclination with respect to 'el-- ement I (Figure 4) and constitutes a support for the music sheets. The latter attheir loweredges are mounted on the upper surface of element 3.

The element 3 is hinged to element I, `by 4a strip I4 of thin fabric which is of a -width to.

extend in close proximity to the side edges of the elements I and 3. I4 is positioned to oppose a partv of the front surface of Ielement I and its remaining portion positioned to oppose the inner part of the upper surface-of theelement 3. The strip I4 is vsecured to the elements I and 3 by any suitable adhesive material. The strip I41will not only constitute a .hinge Afor section 3, but further connects. the

latter to section I. The section 3 when the stand is collapsed folds against the'frontsurface vof The` strip I4if desired-may consist of a length of adhesive tape of suitable width;v

The securing .element A4.is of oblong form, .of a length less ,than the length of and of'a` width corresponding tothe width of element 3. The

element 4 has its lower lengthwise edge I-5 flushl with the lower lengthwise edge I3. and its `side edges flush with the side edges of elementv 3. The element 4 is secured against the inner part of the lower surface of element 3 by thespaced ment 4 centrally thereof is grooved, as at'v III for a purpose to be referred to. The lower lengthwise edge I5 of element 4, when the element 3 is extended relative to element `I has a part thereof abut the front surface of lelement. I :below `element 3. The element 4v depends with respect to element I I'I opens forwardly.

The combined pulling and coupling element 5 consists of a tape of the desired width, length and thickness. The rear end terminal .portion of element 5 is folded uponitself, asat I8, and is arranged centrally, of the lower part of the rear surface of element y2. terminal portion I8 of element 5 .is secured to the element 2 by the holdfast means I9. The element 5 extends across the bottom edge of. element 2 and the lower inner` corner of. ele-V ment -4 when :the stand is extended.v The for,- ward end terminal portion 20 of element 5 is arranged inthe groove I,`I and, itis ,fixedly conextends across the forward lengthwise edge of element 4 and'when the stand is extended, element 5 not only Ybinds against such edge, but alsoagainst the lower surface of yelement 4, lower .inner corner I`1a of the latter and the bottom edgeof element 2'.

It will be assumed that the ystand is in collapsed or foldedposition, such as rshown -in Figure'Z anditisdesiredto extendit. The Ybracing element f2. iszmovedrearwardly at an inclination A portion of the strip' The upper surface of ele-Y and when the ,latter .is arranged in sustaining position, `for the music. sheets, it is Supported in such position Vby. the.- lower inner corner IIa ofelement g4. Thegroove The l.foldedl rear end The element 5.

with respect to the element I or the latter moved forwardly at an inclination with respect to element 2, preferably element 2 will be moved rearwardly with respect to element I, as element 2 moves rearwardly element 5 will be stretched causing it to assume the position shown in Figure 5, that is against the bottom edge of element I, a further rearward movement of elementA 2 will provide for. elements `3 and 4 to assume the position shown in Figure 4, and at which point the stand will be extended to the position shown in Figure 3, with the element Lcoupled with the element 2 by the element 5 and held in an upstanding rearwardly inclined `position, andpwiththe element 3 held in a for- `Wardlyextending :upwardly inclined position relative to element I. When the elements I and 3;.are.;-in;the `inclined positions as aforesaid, they act respectively to sustain and support the music sheetsk when the stand is in extended position and :mounted on 'faedesk or: other support, andat the ysame time, .fthe weight of the-,article or articles f sunportedqby the stand .will be applied to elements ,3. t4....the top of` ,element 2 and the bendZllof `element wherebygthe latterwill be held taut, Aand'zthe:stand@maintained.in extended position when used; The stan d,when in use will not .onlyr be mountedgon .the corner I'Ia of element 4, but also on portion 2;Iand bend 22 ofielem'ent 5..
